Would it be legal to mount a driver's seat using two bolts from the floorboard and then the seatback tie to the roll cage?
Driver’s Seat Sandy
Answer:Under General Regulations, section 6:2, the 2012 NHRA Rulebook states “The driver’s seat of any car in competition must be constructed, braced, mounted, and upholstered to provide full back and shoulder support. The driver’s seat must be supported on the bottom and back by the frame or crossmember. Except as noted in SFI Specifications, seats must be bolted with four bolts (and nuts and washers) on the bottom and one bolt in the rear into crossbar; all bolts must go into frame or crossbraces. Ball-lock pins for seat attachment prohibited in all classes.”
